A person can do good, and also do bad. Reward the good, punish the bad. You're exhibiting black-and-white thinking here and treating "the left" as a monolith. One could just as accurately claim that Elon is attacking "the left" despite "the left" being responsible for the policies that have massively helped Tesla get off the ground.
We should be celebrating that we can now see a way out of this endless trap, and embracing EVs across the political spectrum.
Even in Europe where public transport is arguably better in most places than in the US car ownership rates are still very high and a very large portion of the population is dependent on them.
Even if Tesla does bring the Model 3 to its $30K price range that would still make it price prohibitive to most of the population in the west.
These prices seem to be too much of a shock to the system. It’s better to have a smooth transition over ten years or so.
